My first question would be, what is that gun a rebrand of?
May be just my eyes playing tricks on me but that looks like green hopup knobs, which means G&G.

Ya I believe it is the G&G Max or top tech or what ever they call it. Just not the max price. It's gonna be under $500 full metal with pnumatic blow back. the retailer had some in for demo but sold out already. just waiting for next shipment in a week or so
